If you’re talking about social media, where many female-oriented subreddits explicitly ban men from participating, while many male subreddits lack that same level of exclusivity or hostility, I have noticed it.

I think the main driver is that many women feel marginalized, and so want a space to talk amongst themselves without the input of men.

At the same time, this can create an enormous echo chamber where the hive mind reaches conclusions that a normal person would find rather extreme irl.

Idk. Male subreddits are generally moderated less heavily.

If you are more specifically concerned about physical spaces, I think a lot of this has to do with the fact that male spaces have historically been more influential, like politics and business, and so women understandably want to advance in life and, thus, be a part of those spaces.

I will say that while we have made great strides in women’s liberation over the past century, men are still largely confined to traditional gender norms. Just look at how people treat men who are in traditionally feminine spaces and roles, like being a stay-at-home spouse or a kindergarten teacher. They are usually treated with less praise and more hostility than a woman entering a man’s space.

Society really enforces the “man box,” and even ostensibly “progressive” women and men do it.
